DETAILED DESCRIPTION

The following description and the drawings illustrate specificembodiments to enable those skilled in the art to practice them. Otherembodiments may incorporate structural, logical, electrical, process,and other changes. Portions and features of some embodiments may beincluded in, or substituted for, those of other embodiments. Embodimentsset forth in the claims encompass all available equivalents of thoseclaims.

FIG. 1 illustrates a perspective view of an example generator system 30.The generator system depicted in FIG. 1 includes a front 42, a firstside 44, a rear 46, a second side 48, and a top 50. The top 50 of thegenerator system may include an access panel 52 sized smaller than thetop 50. The access panel 52 may provide access to a radiator systemand/or a coolant tank 22 and cap (illustrated in more detail withrespect to FIG. 3). The generator system 30 generally includes agenerator enclosure and internal components. The generator enclosureincludes four corner posts 34, one located at each corner of thegenerator system 30. The corner posts 34 are extruded L-shaped elementsor bent sheet metal that are rigid and support the enclosure of thegenerator system 30. The adjacent corner posts 34 are connected togetherwith a skid 36. The skid 36 is physically mounted to the corner posts 34for supporting the generator system 30. The skid 36, or base supportmember, may have the same footprint (e.g., dimensions of length andwidth) as the generator system 30. The skid 36 may include one or moreholes 21 (illustrated with caps). The holes 31 allow the generatorsystem to be lifted or otherwise moved (e.g., independently of a fueltank).

In one alternative example, cross-members support the generator system30. There may be a cross-member on each of the front 42, first side 44,rear 46, and second side 48. The cross-members 36 are attached to thebase of the corner elements 34 with a fastener. The cross-members 36 areelongated elements that support the generator system 30.

The front 42 of the generator system 30 includes a front access panel54. The front access panel 54 spans the width of the front 42 from onecorner post 34 to another corner post 34. The front access panel 54extends vertically from the cross-member 36 substantially up to the top50. The front access panel 54 is removably attached to the generatorsystem 30 with latches 55 or another selective coupling device. Removingthe front access panel 54 allows an operator to gain access to theinternal components located at the front 42 of the generator system 30.

Also located on the front 42 is a radiator air intake panel 58. Theradiator air intake panel 58 extends across the width of the front 42from one corner post 34 to another corner post 34. The radiator airintake panel 58 extends vertically from the top of the front accesspanel 54 to the top 50 of the generator system 30. An intake grate 59 isformed in a middle section of the radiator air intake panel 58.

The first side 44 of the generator system 30 as depicted in FIG. 1includes a first side panel 49 that extends from the base of thegenerator system 30 to the top 50. The first side panel 49 may beremovable and server as an access panel. Alternatively, a separateaccess panel, smaller than the first side panel 49 may be located on thefirst side panel 49. The access panel fastens to the first side panel 49with screws or another fastener. The access panel covers an opening inthe first side panel 49. The first side panel 49 also includes a smalleropening through with an exhaust pipe 56 of the generator system 30 mayextend through.

FIG. 2 depicts a rear view of the generator system 30 of FIG. 1. Therear 46 of the generator system 30 includes a rear access panel 53. Therear access panel 53 spans the width of the front 42 from one cornerpost 34 to the other corner post 34. The rear access panel 53 extendsvertically from the skid 36 substantially up to the top 50. The rearaccess panel 53 is removably attached to the generator system 30 withlatches 55. Removing the rear access panel 53 allows an operator to gainaccess to the internal components located at the rear 46 of thegenerator system 30.

Located on the rear 46 above the rear access panel 53 is an exhaustpanel 64. The exhaust panel 64 extends across the width of the front 42from one corner post 34 to the other corner post 34. The exhaust panel64 extends vertically from the top of the rear access panel 53 to thetop 50 of the generator system 30. An exhaust grate may be formed in amiddle section of the exhaust panel 64.

Also depicted in FIG. 2 is the second side 48 of the generator system30. The second side 48 includes a ventilation intake panel 62, which maybe referred to as a side panel. The ventilation intake panel 62 spansthe width of the second side 48 from one corner post 34 to the othercorner post 34. The ventilation intake panel 62 may extend verticallyfrom the bottom of the generator system 30 substantially up to the top50. The ventilation intake panel 62 may be fastened to the corner posts34 with screws.

The ventilation intake panel 62 includes a lower air intake 69. Thelower air intake 69 may be a grate formed in ventilation intake panel 62to allow air to flow through the ventilation intake panel 62 to cool thealternator.

Located above the lower air intake 69 is an upper air intake 63. Theupper air intake 63 may be a grate formed in the ventilation intakepanel 62 to allow air to flow through the ventilation intake panel 62for engine 66 cooling and combustion. The upper air intake 63 and lowerair intake 69 are configured to mate with an intake duct 70 locatedinside the generator system 30.

In one alternative, the ventilation panel 62 may be divided into a sidepanel at the lower part of the generator system 30 and a cover panel atthe upper part of the generator system 30. The cover panel may span fromone corner post 34 to the other corner post 34 and from the ventilationintake panel 62 to the top 50.

Depicted in both FIGS. 1 and 2 is the top 50 of the generator system 30.The top panel 50 is configured to extend from the rear 46 to the front42, and from the first side 44 to the second side 48. The top panel 50may be flat panel or a dome-like configuration. The top panel 50 issized to cover the top of the generator system 30 to protect thegenerator system 30 from weather elements.

Referring to FIG. 3, the generator system 30 depicted includes twoseparate compartments, an upper compartment 45 and a lower compartment47. The two compartments are separated by a channeling panel 74, whichdivides the internal portion of the generator system 30 into the twoseparate compartments. The upper compartment 45 may also be referred toas a plenum, meaning a separate space from an engine 66 and analternator 68 provided for air circulation of the generator system, andthe upper compartment 45 is defined by a channeling panel 74 on thebottom, the front 42, the first and second sides 44, 48, the rear 46,and the top 50. The lower compartment 47, which includes the engine 66and the alternator 68, is defined by the channeling panel 74 on the top,the front 42, the first and second sides 44, 48, the rear 46, and thebase 65. The lower compartment 47 may also include electric controls 23for controlling the engine 66 and/or the alternator. The uppercompartment 45 and the lower compartment 47 are vertically arranged. Inone example, the horizontal cross sectional area of the uppercompartment 45 is substantially aligned with the horizontal crosssectional area of the lower compartment.

The electric controls 23 may include user input mechanisms, a controlcircuit, a controller, and one or more power components. The user inputmechanisms may include a key pad, a touch screen, or a shutoff switch.The key pad or the touch pad may receive user input codes for settingsof the generator system. The setting may specify engine speed, generatoroutputs, or operation profiles. The operation profiles may control oneor more fans of the generator system 30 to control air flow through thegenerator system 30. That is, the operation profile may include a timingcontrol for one or more fans of the generator system 30. The shutoffswitch may turn off the throttle of the generator system 30 to turn offthe generator system.

The controller may receive user commands and calculate a generatorcommand for operation of the engine 66 and/or the generator 68. Thegenerator command may instruct the engine 66 to a specified speed ortorque. The generator command may instruct the alternator 68 to aspecific frequency or load. The generator command may be sent to anexternal system controller or another generator controller.

The channeling panel 74 is a planar panel internal to the generatorsystem 30. The channeling panel 74 extends from the front 42 to the rear46 and from the first side 44 to the second side 48. The channelingpanel 74 creates a water barrier between the upper compartment 45 andthe lower compartment 47. The channeling panel 74 separates the remoteradiator system from the engine 66 and alternator 68 of the generatorsystem 30.

The channeling panel 74 may include an air flow opening 76 between theupper compartment 45 and lower compartment 47. The air flow opening 76is configured such that water does not enter the lower compartment 47through the opening 76. The water barrier function of the channelingpanel is more fully described below.

The channeling panel 74 may be a planar panel. The channeling panel 74may be sloped from the front 42 to the rear 46 or the channeling panel74 may be substantially horizontal or level. The term substantiallyhorizontal may be defined as perpendicular to the direction of gravityor within a predetermined angle of the direction of gravity (e.g.,within 1 degree). The channeling panel 74 may be sloped in anotherdirection. The channeling panel 74 may be sloped to direct water thatcollects within the upper compartment 45 to the rear 46 of the generatorsystem 30 where it may be directed out of the upper compartment 45.Water that is directed down the slope of the channeling panel isdirected to drainage holes.

In one example, drainage holes may be located as through holes in theexhaust panel 64, integrated into the channeling panel 74, or bedirected through an exhaust grate. The water flows through the holesoutside of the generator system 30 and down the sides.

The upper compartment 45 includes a remote radiator system 80 for theengine 66. The remote radiator system 80 includes a cross-panel 82. Thecross-panel 82 extends from the first side 44 to the second side 48within the upper compartment 45. The cross-panel 82 includes an openingor grate area in the middle to allow air to pass through the cross-panel84.

Attached to the cross-panel 82 are one or more section panels 84 thatextend from the cross-panel 82 to radiator intake panel 58. The sectionpanels 84 contact the radiator intake panel 58 on each side of the grate59, forming a cavity 75. A radiator fan 90 is mounted within the cavity.The radiator fan 90 is configured to draw air from outside the generatorsystem 30 in through the lower air intake 69 and into the cavity 75.

A remote radiator 81, as illustrated in FIG. 5, is connected to thecross-panel 82 on a side opposite the cavity 75. The radiator 81 may bea standard radiator used to exchange heat from the engine 66 to theatmosphere through a cooling fluid, thereby regulating the enginetemperature. The remote radiator 81 may include an upper tank 22 forstoring the cooling fluid, or a portion (e.g., excess) of the coolingfluid. The upper tank 22 may include an inlet. The inlet may beconnected to the cooling fluid outlet of the engine 66 through an outlethose and accepts the heated cooling fluid from the engine 66.Alternatively, the radiator 81 may also include tanks on the side of theradiator 81.

The remote radiator 81 may include a core, where air flow passes throughthe core and cools the cooling fluid. The remote radiator 81 may alsoinclude a bottom tank. The bottom tank may include an outlet. The outletmay be connected to the cooling fluid inlet of the engine 66 through aninlet hose. The cooled fluid passes from the remote radiator 81, exitingthrough the outlet and traveling through the inlet hose to the engine.Both the inlet hose and outlet hose will be an extended length in orderto connect the remote radiator 81 to the engine 66.

The remote radiator system 80 may also include a catch basin below theremote radiator 81. The catch basin may be located directly under theremote radiator to collect any fluids, cooling or otherwise, that leakfrom the radiator and direct them away, thereby preventing fluid fromentering the lower compartment. 47.

The upper compartment 45 also includes an exhaust duct cavity 92containing an exhaust fan 100. The exhaust duct cavity 92 is the areadefined by the radiator intake panel 58, the first side panel 49, thecross-panel 82, and the adjacent section panel 84. The channeling panel74 includes an opening or cutout 76 in the area defined by the exhaustduct cavity 92. The opening 76 creates an air flow path from the lowercompartment 47 into the exhaust duct cavity 92 of the upper compartment45. The connection between the cross-panel 82 and the adjacent sectionpanel 84 are made water tight or otherwise sealed to prevent water fromleaking into the lower compartment 47 at the exhaust duct cavity 92.

Mounted within the cross-panel 82 portion of the exhaust duct cavity isthe exhaust fan 100. The exhaust fan 100 will be further described belowin connection with FIGS. 4, 7, and 8. The muffler 104 is also foundwithin the upper compartment 45 depicted in FIG. 3. The muffler isfurther described below in connection with FIG. 5.

As illustrated in FIG. 3, the lower compartment 47 includes the engine66. The engine is mounted to the base 65 to secure it within thegenerator system 30. The engine 66 may be an internal combustion engine.The engine 66 may include external components such as crankshaft,flywheel, muffler 104, air cleaning system, and a control portion. Theengine 66 may be a two-stroke engine or a four-stroke engine. The numberof cylinders of the engine 66 may vary to include one cylinder ormultiple cylinders. The size of the engine 66 may vary depending on theapplication.

The engine 66 may be any type of engine in which the combustion of afuel (e.g., gasoline or another liquid fuel) with an oxidizer (e.g.,air) in a chamber applies a force to a drive component (e.g., piston,turbine, or another component) of the engine 66. The drive componentrotates to turn a drive shaft. The drive shaft of the engine 66 may beconnected to an alternator 68.

The alternator 68 is operated by rotation of the drive shaft to turn thealternator 68 and produce electric output. The alternator 68 includes analternator fan 71. The alternator fan 71 functions to draw air over thealternator 68 to cool the alternator 68.

Also located in the lower compartment 47 is the intake duct 70. Theintake duct 70 includes two sections, an upper duct 77 and a lower duct78. The intake duct 70 will be described further in relation to FIG. 6below.

FIG. 4 illustrates a front view of the perspective of FIG. 3. Shown inFIG. 4 is the exhaust fan 100 discussed above. The exhaust fan 100 ismounted within the cross-panel 82. The exhaust fan 100 functions to drawair from the lower compartment 47 into the exhaust duct cavity 92. Thefunction of the exhaust fan 100 is described below in connection withthe function of the generator system 30.

FIG. 5 illustrates a first side 44 of the generator system 30. In FIG.5, the upper compartment 45 and lower compartment 47 is shown. Thechanneling panel 74 is depicted as dividing the upper compartment 45 andlower compartment 47. The channeling panel 74 may also be referred to asa divider or separating element

As can be observed in FIG. 5, the channeling panel 74 may besubstantially horizontal, but alternatively may include the slope asdiscussed above. The channeling panel 74 on the side adjacent the front42 is vertically higher than the side adjacent the rear 46 of thegenerator system 30. The slope of the channeling panel may be in therange of 1/16 of an inch per foot to 1 inch per foot. Alternatively, thechanneling panel may be orientated at an angle in the range of 5 to 25degrees from the drainage point.

The channeling panel 74 may also be sloped in any direction within thegenerator system, so long as a flow path for water is created to directwater out of the upper compartment 45 and out of the generator system30.

Also illustrated in FIG. 5 in the upper compartment 45 is the remoteradiator system 80, including the remote radiator fan 90 and radiator81. As illustrated in FIG. 5, the radiator fan 81 is connected to thefan support panel 86 on one side. The opposite side of the fan supportpanel 86 includes the remote radiator 81 connected thereto.

The muffler 104 located in the upper compartment 45 is also depicted inFIG. 5. The muffler 104 may be physically connected to the channelingpanel 74 directly through a rivet, bolt, or another connector. Themuffler 104 may alternatively be connected to upper compartment 45 via amounting bracket. The mounting brackets may connect to a mounting barthat is attached to the first side 44 and second side 48 of thegenerator system 30.

As illustrated in FIG. 6, the muffler 104 is connected to the engine 66via an exhaust pipe 102. The exhaust pipe 102 extends from the muffler104 in the upper compartment 45 down into the lower compartment 47 andis connected to the engine 66. The exhaust pipe 102 passes through thechanneling panel 74 through an opening in the channeling panel. A watertight seal may be maintained between the exhaust pipe 102 and channelingpanel 74. This water tight seal may be created to prevent water in theupper compartment 45 from draining into the lower compartment 47.Alternatively, the channeling panel may be formed with a raised-liparound the opening to prevent water from reaching the opening andflowing into the lower compartment 47.

FIG. 6 illustrates a view from the front 42 of the generator system 30with a cut-away of the intake duct 70. The intake duct 70 includes anupper duct 77 and a lower duct 78. Located within the upper duct isupper channel 83. The lower duct 85 includes a lower channel 85.

The upper duct 77 is in communication with the upper air intake 63depicted in FIG. 2. The upper duct 77 is attached to the ventilationintake panel 62 just below the upper air intake 63. The upper duct 77extends vertically at an angle away from the ventilation intake panel62. Sides 87 are connected to the vertical edges of the upper duct 77.The sides 87 extend from the upper duct 77 to the ventilation intakepanel 62. The top of the upper duct 77 is open to the lower compartment47. The upper duct 77 and sides 87 enclose the upper duct 77 about theventilation intake panel 62, creating the upper channel 83 between theventilation intake panel 62 and the upper duct 77.

The upper duct 77 and upper channel 83 provide the main source ofcooling airflow for the lower compartment 47 and combustion for theengine 66. The upper duct 77 may also provide cooling of the electriccontrols 23 located adjacent the opening of upper duct 77 inside of thelower compartment 47. The electric controls may include circuits,controllers, capacitors, breakers, or other components that generateheat. The upper channel 83 is further configured to provide the properamount of air volume to supply the engine with sufficient air forcombustion and operation of the engine 66.

Illustrated in FIG. 6, the lower duct 78 is in communication with thelower air intake 69 depicted in FIG. 2. The lower duct 78 is attached tothe ventilation intake panel 62 just below the lower air intake 69. Thelower duct 78 extends vertically at an angle away from the ventilationintake panel 62. The sides 87 connected to the upper duct 77 extend downto the base and are additionally connected to the lower duct 78. Thesides 87 extend from the lower duct 78 to the ventilation intake panel62. The top of the lower duct 78 is open to the lower compartment 47.The lower duct 78 and sides 87 enclose the lower duct 78 about theventilation intake panel 62, creating the lower channel 85 between theventilation intake panel 62 and the lower duct 78.

The lower duct 78 and lower channel 85 establish a directed pathway forproviding airflow across the alternator 68. Air from the lower duct 78reaches the inlet of the alternator 68 to cool the alternator 68. Airfrom the lower duct 78 may also provide cooling for the engine 66. Theair pulled though the lower channel 85 is sufficient to maintain thealternator 68 at a proper operational temperature.

The above described generator system 30 functions to provide a reducedfootprint, using less square footage through the implementation of theremote radiator system 80. The disclosed remote radiator system 80 andventilation are housed within the upper compartment 45 to allow for asmaller footprint of the generator system 30.

As illustrated in FIG. 7, the remote radiator system 80 operates tointroduce air from outside the generator system 30 into remote radiatorsystem 80 in the upper compartment 45. In operation, the radiator fan 90is switched on and acts to pull air from outside in through the intakegrate 59. Airflow 120 enters the remote radiator system 80 and continuesover the blades of fan 90. Air 122 exits the radiator fan 90 and ismoved through the radiator 81. The air 124 entering the remote radiator81 acts to cool the cooling fluid of the remote radiator 81. Air movesout of the radiator 126 and into the exhaust compartment 101. Air thathas entered the exhaust compartment 101 continues to flow toward therear 46 of the generator system 30. In doing so, the air flows over themuffler 104. The air flow over the muffler works to cool the muffler andreduce the surface temperature of the muffler as well as the exhaustcompartment 101. The air 128 exits the generator system 30 through anexhaust grate formed in the exhaust panel 64.

As illustrated in FIG. 8, the disclosed generator system 30 alsoincludes ventilation and combustion airflow for the engine andalternator within the lower compartment 47.

The lower compartment 47 ventilation functions to cool the alternator 68and engine 66 by drawing air into the lower compartment 47 through theupper air intake 63 and lower air intake 69. Air 140 enters the lowerduct 78 and flows through the lower channel 85. Air is drawn into thelower channel 85 initially by the alternator fan 71. The alternator fan71 causes the air to flow over the alternator to cool the alternator. Atthe same time, the exhaust fan 100 in the upper compartment 45 isassisting the alternator fan 71 in drawing air in the lower compartment47. Accordingly, the exhaust fan 100 should be sized to accommodate theload associated with the lower duct 78 and upper duct 77 as describedbelow. Air that has been drawn into the bottom of the lower compartment47 by the alternator fan 71 is pulled towards the exhaust fan 100. Airthat flows over the alternator 66 also flows over the engine 66 as theexhaust fan 100 rotates, pulling the air towards the exhaust fan 100.

Also illustrated in FIG. 8, the rotation of the exhaust fan 100 alsodraws air 150 from the outside and into the lower compartment 47 throughthe upper air intake 63. Air drawn through the upper air intake 63travels into the upper duct and through the upper channel 83. Air 150pulled through the upper duct 77 travels towards the exhaust fan. As theair travels towards the exhaust fan it flows over the engine 66 andother components in the lower compartment to cool them. Air 150 providescooling for the entire lower compartment 47. Combustible air is alsoprovided to the engine air intake 72 by this air flow from air 150.

As illustrated in FIG. 9, air 140 and 150 mix and are pulled towards theexhaust duct cavity 92 by the exhaust fan 100. Air 114 d from the lowercompartment 47 is pulled into the exhaust duct cavity 92 by the exhaustfan 100. Air that in the exhaust cavity 92 is pulled through the exhaustfan 100 and pushed into the exhaust compartment 101. Air that enter theexhaust compartment 101 from the lower compartment 47 joins the air 126exiting the remote radiator system 80. The combined air flows over themuffler 104. The air exits the generator system 30 through an exhaustgrate 67 formed in the exhaust panel 64.

The above described generator system 30 additionally functions to reduceor eliminate the infiltration of rain water into the lower compartment47. As outlined by safety standards, water may not be permitted to enterthe AC voltage area, i.e. the lower compartment 47 of the generatorsystem 30. The separation of the upper compartment 45 which may includerain water ingress from the upper compartment 45 prevents water fromentering the lower compartment 47.

As described above, the channeling panel 74 creates a water barrierbetween the upper compartment 45 and the lower compartment 47. Thebarrier prevents rain water existing in the upper compartment 45 fromentering the lower compartment 47. As rain water may enter through theradiator intake 58 or the exhaust grate 67, the water is directed viathe slope of the channeling panel 74 to the rear 46 of the generatorsystem 30 and out holes in the generator system 30. Water directed tothe rear 46 may be directed out of the generator system 30. Directingwater out of the generator system 30 prevents water from entering thelower compartment 47.

As referred to above, the above described generator system 30 reducesthe footprint of the generator system by placing the radiator system 80on top of the alternator 68 and engine 66. A reduced footprintconfiguration is particularly well suited for telecom usage where spaceis at a premium. In use, the generator system 30 may be placed adjacenta telecom structure in order to provide power to the telecom system,i.e. a cellular tower. A telecom structure may be secured to a concretepad or placed on a metal structure. The reduced footprint results in areduced use of square footage adjacent the telecom structure that isneeded.

FIG. 10 illustrates the generator system 30 as depicted in FIG. 1 andincluding a fuel tank 103. The generator system 30 sits on top of thefuel tank 103. The fuel tank 103 supplies fuel for the engine 66 of thegenerator system 30. The fuel tank 103 is substantially the same size asthe footprint of the generator system 30. Utilizing the fuel tank 103with the same or similar footprint of the generator system 30 ensuresthat no more area is needed to install and utilize the generator system30. Below the fuel tank 103 may be a fuel tank base 105 configured tosupport the fuel tank 103. The fuel tank base 105 may have the samedimensions or footprint as the fuel tank 103. The footprint may be atleast two dimensions (e.g., length and width). Substantially the samefootprint may be within a predetermined portion of each other (e.g., thelength of the fuel tank and the width of the fuel tank are each within apercentage such as 2% or 5% of the dimensions of the upper compartment45 and the lower compartment 47. The fuel tank base 105 may include oneor more slots 106 for lifting the fuel tank 103 or the entire generatorstructure including the fuel tank 103 and the generator system 30. Theslots 106 may be rectangular or shaped for mating with a forklift.

FIG. 11 illustrates an example method for manufacturing the generatorstructure of FIGS. 1-10. Additional, different, or fewer acts may beincluded.

At act S101, at least an alternator 68 and an engine 66 in a lowercompartment of the generator structure. The alternator 68 and the engine66 may be secured to a skid 36. The alternator 68 and the engine 66 maybe mounted to the skid using one or more mounting brackets andconnectors such as bolts with rubber isolators. The skid may includeholes at mounting locations defined according to the size or model ofthe generator. The bolts with rubber isolates may be screwed into theskid and the generator to physically connect the skid and the generatorbut allow some relative movement. The amount of relative movement may bedefined by the dimensions and/or material of the rubber isolators. Theskid may be configured for transportation on a vehicle or rails.

At act S103, at least one cooling device configured to cool the lowercompartment is mounted in the upper compartment using one or moremounting brackets and connectors such as bolts with rubber isolators.The rubber isolators cushion the connection between the at least onecooling device and the lower compartment and allow small amounts ofmovement between the at least one cooling device and the lowercompartment. The cooling device may include a radiator, one or morefins, and/or a heat exchanger.
